  • 30-Day Home Trial
  • One Year Limited Warranty
  • AlterPay Financing
  • Health and Fitness Rewards

Alter System and Membership

The Alter System includes the following products:

  • Alter DNA/Genetic Trait Report — Includes an at-home oral swab and an Alter DNA report, providing a personalized approach to fitness, wellness, and stress management. Your Alter DNA report also includes a free report walkthrough with an Alter senior wellness advisor.
  • Alter Signal — A wearable biometric device that tracks sleep, stress, activity, and heart rate. The device pairs with the Alter Screen and Alter App.
  • Alter Screen — An AI-powered mirror that offers workouts for all fitness levels, as well as AI form correction, allowing you to exercise in a safer and smarter manner.
  • Alter Accessories — Additional accessories include a foam roller, yoga mat, and strength bands.

When you purchase an Alter system, your membership is included. Alter membership includes access to a variety of content and coaching only available to members. Currently, the Alter System and membership is priced at $2,995 (reduced from $3,199).

Alter App

The Alter App pairs with your Alter Signal and Alter Screen devices and allows you to track your health and wellness goals. The app is available on both iOS and Android devices.

30-Day Home Trial

If you aren’t satisfied with your Alter System, you can receive a full refund within 30 days of delivery. You will need to return the system in its original condition and in its original box to activate your refund.

One Year Limited Warranty

The Alter System is protected by a one year limited warranty that covers the Alter Signal and Alter Screen devices — both devices are warranted to be free from defects in materials and workmanship for a period of 12 months from the date of delivery.

AlterPay Financing

The upfront cost of an Alter system and membership is currently $2,995. The company understands that this may be a significant upfront investment for some customers; thus, Alter offers zero percent APR financing through its AlterPay financing program. 

Eligibility restrictions may apply, but the majority of customers will be approved, no matter their credit score or financial history. AlterPay financing offers monthly payments as low as $79.95 per month with no extra fees; your down payment can be customized based on your needs.

Health and Fitness Rewards

To encourage Alter members to meet their health and fitness goals, Alter will cover your monthly membership fee if you complete your Alter plan each week.

The Bad

  • Alter System and Membership Cost
  • Devices and Membership Not Sold Separately

Alter System and Membership Cost

The Alter System, including membership, currently costs $2,995 (reduced from $3,199). For some customers, this may be a daunting price tag. However, it is important to keep in mind that this price includes your DNA kit, the Alter Signal biometric wearable device, the Alter Screen, additional accessories, and your membership. To assist in making Alter’s services available to a wider audience, Alter offers financing through its AlterPay program. AlterPay allows you to make monthly payments of $99 with zero percent APR, providing a simple alternative to paying the full upfront cost out of pocket.

Devices and Membership Not Sold Separately

Alter System devices and Alter membership are not sold separately; they are currently only available in a bundled plan with one price. Thus, if you would just like to, for example, purchase the Alter Screen to augment your current workouts, you will have to purchase the complete Alter System and membership.

However, it is important to note that the Alter System and membership is designed to provide you with a well-rounded approach to your health and wellness based on your DNA, and all devices support one another in helping you reach your goals.

Lisa Marie

I'm new to trying this product, I've only been using it for a week. While the concept is intriguing, the product falls short in key areas. First, comfort is an issue. The wrist band and arm band are made of fabric, with a Velcro closure. The strap is stiff and irritating. Wearing it for extended periods of time is not pleasant. Accuracy is another concern. The tracker frequently undercounts or overcounts my steps. I also wear a Garmin device and the numbers are never even close to being the same. The only thing comparable between the two, is my sleep pattern. For a product marketed as data-driven and precise, this is frustrating. On the positive side, the DNA insights were interesting, providing tailored advice on nutrition and workout routines. However that information is only helpful if paired with a reliable tracking device-and this one isn't. For the price, I expected bett

The mirror workouts are engaging and challenging. I’ve definitely seen progress, but I do wish customer support was a little quicker to respond. Sometimes it takes a while to get the help I need, which can be a bit frustrating when I’m dealing with technical issues.

At 45, I realized it was time to take my health seriously if I wanted to be around for my grandchildren. Alter’s personalized coaching and DNA insights made the process so much easier.

It feels like I’m adding years to my life!
